Marlin Mountie .22 LR is the one I reach for the most in the lever actions department:

That said, I do have a couple others currently:

A Marlin "Limited". Which was a limited edition straight stock 16" run of 1600 each in 45 Colt and 44 Mag. Mine is in .44 magnum.

The other one is another 16" gun. A 336, in 30-30. Depending on which person you talk to, it was either referred to as a Marauder or a Texan. No matter to me, I just like the handling characteristics of it, and have mounted a couple different optics on it playing around. It currently wears a red dot.
